ORE-CONCENTRATOR.

.PCIFICATION forming part of Letters Patent No. 345,114, dated July G, 1886.

Application filed Muy 23, i855. Serial No. 166,523. (No model.)

To alb whom it may concern:

Beit knownthat we,- R. NnILsoN CLARK and Nonnis l-I. Conn, citizens of the United States, residents of Leadville, in the county of Lake and State ol` Colorado, have invented certain new and useful Improvements in Ore-Concentrators; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention has relation to improvements in ore-concentrators.

The invention is designed as an improvement upon the invention covered by the patent granted to us October 2, 1883, No. 285,970; and the novelty consists in the construction and combination of devices, as will be hereinafter more fully set forth and claimed.

In the accompanying drawings, illustrating our invention, Figure l is a transverse sectional View of our machine taken on the lines x x of Fig. 2. Fig. 2 is a plan view ofthe machine, and Fig. 3 is a sectional detail view of the means for adjusting the bar T with the camwheel V in position.

Referring by letter to the said drawings, a a indicate the tables for receiving the ore. These tables are supported on legs b at their heads, and on similar legs at their feet, which are hinged at their upper ends to the under sides of the tables in such a manner as to allow lateral movement of the latter. The legs at the heads of the tables are provided at a suitable distance from their lower ends with shoulders c,and their said lower ends pass through vertical apertures inthe beam B of the main frame, with the shoulders a. normally resting thereon. In practice the legs at the head of the table might be of a little greater length than those at the foot, so as to give the table an ineline 'from head to foot.

C C indicate brackets or hangers, which are rmly secured to the beam B at the head portions of the tables and extend a suficient distance below the same. To the lower ends of these brackets are pivoted horizontal bars D D,which lap each other at their inner meeting ends and bear upwardly against the head legs .b at their outer ends.

E E indicate threaded adj nsti ng-rcds,\vhich work in threaded bearings lin the beam B. These rods engage the meeting ends of the bars D, and are provided at their upper ends with handwhcels e. By this construetion'it will be seen that by turning the rods E down upon the meeting ends of the bars D the legs b will be raised, and, consequently, the heads of the ta bles, thereby giving the same the desired iuclination.

F F indicate vertical standards ofthe main frame, and G Gr transverse beams thereof, which furnish supports for the bearings of the knoeker-shal't II',which may be turned by any suitablemeans. ThestandardsFareprovided at their upper ends with brackets f, which piv otall y support bell-crank levers I I. These bell-crank levers are connected by their heri- Zoutal branches, by means of links a, with vertically-moving bars T, and by their vertical branches, through the medium of the connecting-arms S and Z, with the sides ofthe tables. The outer ends of the bars T are made' adjust able by means of threaded rods y, which are secured to the main frame at their lower ends. These rods are provided with hand-wheels, Z, at their upper ends,which carry sleeves passing through apertures in the said bars T, and provided with internal threads to engage the threads of the rods. By this construction it will be seen that the bars T being allowed to move on the sleeves of the hand-wheel Z, by bringing the said wheels down on the rods y, so as to limit the rise of the outer ends of the bars T, the throw of the opposite ends of the said bars will beincreased, and, consequently, the lateral movement of the tables. IVhen the wheels Z are turned in the opposite direction, the throw of the bars T and movements of the tables will be lessened.

K Ii indicate horizontal rods, which are secured at their inner ends to the standards F of the main frame, and supported transversely beneath the tables in suitable brackets, a, so as to move in the said brackets. are secured at their inner ends to the standards F, and are provided at orl near their outer ends with nuts or collars which serve as stops for the outer ends of the spiral springs L, sur- These rods rounding the said rods K. The tables are provided with bumping-blocks N, which Strike the uprights F, when the tables are returned by the action of the spring L.

h indicates the distributing-boards at the heads of the tables,for receiving the pulp and clear water. These distributingboards are separated into compartments, so that three grades of ore may be distributed 0r operated on at once, if desired; and an equal number of hoppers or receptacles are at the opposite ends or feet of the tables.

In operation,when the shaft H is rotated, the cam-wheels V strike the bars T and drive the same upwardly at regular intervals. When the bars T are moved n p, thc bell-crank levers are turned in their bearings, and through the medium ofthe connecting-arms S and Z move the tables laterally in opposite directions. As the points n of the cam\vheels or knockers pass the Wear-blocks w on the under sides of the bars T, the springs L Will be allowed to expand, and by their action against the brackets ai will bring the tables to their normal positions, the bell-cranks and connectingarms acting simultaneoi'isly to depress the bars T. By the constant rotation of the shaft and the knockers thereon the tables will be given a jarring and lateral reciprocating movement and the ore divided in its passage down the incline tables.

Having described this invention, what we claim isl. The combination,with the main frame, o the tables, hinged legs, hangers secured to the the vertically-moving bars, bumping-blocks,

the uprights, means for connecting the bars with the tables, and means for adjusting the movement of the said bars, substantially as specified.

L The combination,with the uprightsF and the main frame, of the bars T, the knockers, rods y, and hand-wheels Z, having the sleeves passing through the said bars, the tables, and means, substantially as described, for connecting the bars with the tables, all adapted to serve in a concentrator, substantially as speci- Y lied.

In testimony whereof we ailix our signatures in presence of two witnesses.
